Abstract

In this paper, a new variation of current mode control for a high power factor boost rectifier is presented. The general features are- no input voltage sensing; no use of multiplier; and no inner current regulator. It therefore follows the same control structure as that of linear peak current mode control (LPCM) and nonlinear carrier control (NLC). However it implements a different equation for the modulator that extends the range of continuous conduction mode (CCM) of operation. The controller is predictive as the actual current equals the reference current at the end of each switch period.
